摘要
The reaction of sym-dimethyltetraphenyl carbodiphosphorane (CDPMe) with [Ni(CO)4] under standard conditions yields the CDPMe- and carbon monoxide-bridged dinickel pentacarbonyl complex [Ni2(CO)4(µ2-CO)(µ2-CDPMe)] (2). However, under an atmosphere of CO(g), reaction of [Ni(CO)4] with CDPMe gives the primal target complex [CDPMe-Ni(CO)3] (3). The complexes were examined in solution (ESI-MS, NMR) and in the solid state (IR, X-ray diffraction analysis). The resulting Tolman electronic parameter (TEP) and percentage buried volume value (%Vbur) of CDPMe are presented and compared with hexaphenyl carbodiphosphorane (CDPPh). DFT calculations were performed to analyze the bonding situation in complexes 2 and 3.
